New image captures galaxy cluster emerging from cosmic web

The tumultuous evolution of a galaxy cluster captured close to its formation in the cosmic web

An international team of astronomers using the National Science Foundation’s Green Bank Telescope (GBT) in Green Bank, West Virginia, and the NASA’s Chandra X-ray Observatory have captured a snapshot of a massive galaxy cluster, very close to the epoch when it began to emerge from the cosmic web.

When it comes to the Universe, there is more than meets the eye. Astronomers using the National Science Foundation’s Green Bank Telescope (GBT) have discovered a massive, previously unknown structure in our Galaxy. This discovery was so unexpected, additional observations were taken using the Green Bank Observatory’s 20-meter Telescope to confirm the data.

How long is a day on Venus? Scientists crack mysteries of our closest neighbor

Fundamentals such as how many hours are in a Venusian day provide critical data for understanding the divergent histories of Venus and Earth, UCLA researchers say. Credit: NASA/JPL-Caltech

Venus is an enigma. It’s the planet next door and yet reveals little about itself. An opaque blanket of clouds smothers a harsh landscape pelted by acid rain and baked at temperatures that can liquify lead.

Now, new observations from the safety of Earth are lifting the veil on some of Venus’ most basic properties. By repeatedly bouncing radar off the planet’s surface over the last 15 years, a UCLA-led team has pinned down the precise length of a day on Venus, the tilt of its axis and the size of its core. The findings are published today in the journal Nature Astronomy.

New astronomical survey utilizes the Green Bank Telescope to give clearest view of ionized gas in the Milky Way

Astronomical surveys mapping regions of the Galaxy have been collected and studied for decades. These surveys allow researchers to compare previous data, further characterize objects or images of the sky, and learn more through statistical analysis.  For the National Science Foundation’s Green Bank Telescope (GBT) Diffuse Ionized Gas Survey (GDIGS), researchers took advantage of the power of the GBT, located in Pocahontas County, West Virginia, to better understand the impact of massive stars in the Milky Way.

West Virginia Students Contact International Space Station LIVE

How would you feel if you could talk to an astronaut, orbiting over 200-miles above you in space?

Friday, May 7th at 8:00 AM EDT, students in rural West Virginia will experience this once in a lifetime opportunity. Green Bank Elementary-Middle School (GBEMS) will be contacting astronaut Mark Vande Hei on the International Space Station (ISS).

Can Green Bank Telescope Defend Against Asteroid Apophis?

The National Science Foundation’s Green Bank Telescope (GBT) is teaming up with NASA’s Goldstone Deep Space Communications Complex (GDSCC) to observe this potentially hazardous asteroid. These new observations of Apophis will allow scientists to improve their understanding of the asteroid’s orbit, and better estimate the odds that Apophis could strike the Earth in the future. Predicting if there is a real chance of impact, decades ahead of time, gives scientists the opportunity to take action to manipulate the orbit of Apophis to avoid a collision in the future.

This “waterfall image” is actually three separate observations combined to show NASA’s Mars Perseverance rover as it enters the Martian atmosphere before touching down on the red planet. Green Bank Observatory Data Analyst Amber Bonsall created this image using data received by the Green Bank Telescope (GBT). The GBT was pointed at Mars to observe communications from the rover as it landed February 18th, 2021 at 3:55 p.m. EDT.

COVID-19 Safety Operations

In response to the health concerns posed by COVID-19, the Green Bank Observatory has made changes to its public programs and events.

Learn more about how to access the Science Center, bus tours, and other guided programs here.

Tour tickets are required to enter the Science Center. These can be purchased at our online store.

Masks are required to be worn by those two years and older over nose and mouth while inside Science Center, buses, and participating in any of our activities. THIS IS STRICTLY ENFORCED FOR THE SAFETY OF OUR STAFF AND ALL VISITORS.

Virtual tours, live streams, and video updates on Observatory news and education are also available, tune in here.

As these operations continue to evolve, please check back for updates.

Take a FREE self-guided walking tour on site. Hiking and biking are welcome. An observation deck to view the Green Bank Telescope is located in the Jansky Lab parking lot. You can download and print a map for a self guided walking tour here.

Learn more about biking onsite here.

Visit the Galaxy Gift Shop online.

Try these educational resources and activities at home.

Our instruments are extremely sensitive, and many operate 24-hours a day. Smart phones, digital cameras, fitness trackers, and other electronic devices can interfere with observations. Our scientists thank you for leaving these powered off in your vehicle!

Educational groups scheduled for visits and programs in 2021 that are affected by this change in operations will be contacted directly. Virtual visits are being offered for groups, learn more here. If you have questions, please contact our Education staff directly at reservations@gbobservatory.org.

Student Summer Research Programs at GBO & NRAO Get a Boost from Going Remote

The summer research programs at the National Radio Astronomy Observatory (NRAO) kicked off in May 2021 with a significant increase in participation. This year’s program welcomed 65 students across all partner locations, a nearly 67-percent increase over the prior year. NRAO and the Green Bank Observatory (GBO) also welcomed 45 mentors to the summer programs—a record number—many of whom are first-time or early-career mentors.
